Hi all,
Supposedly my router is itself streaming traffic to clients. Is it possible
for it to mark its packets before going through dsmark??
I have gone through the examples in iproute2/examples, i noticed that
there's always an ingress and egress of which these are 2 different dev. Is
it possible for before ingress and egress be the same dev??
I tried the script below but doesn't seem to work... How to control the
bandwidth in this case??
I want to show that AF11, AF21, AF31, AF41, EF, BE traffic has different
throughput if 6 fullstreams of traffic is push out from server to client
(with 6 different ports).
eg:
#! /bin/sh -x
#
device="eth1"
client0="192.168.1.1/32"
client2="192.168.1.20/32"
/sbin/ipchains -A output -i $device -p tcp -s $client0 -d $client2 --sport
42010 -m 1
/sbin/ipchains -A output -i $device -p tcp -s $client0 -d $client2 --sport
42012 -m 2
/sbin/ipchains -A output -i $device -p tcp -s $client0 -d $client2 --sport
42014 -m 3
